Newbie Question Sha512 Password not found

I am a complete newbie but would appreciate some guidance as to what I am doing wrong.

I have a SHA512 hash taken from a Linux user password. The password was set to 12345

I have saved this in a file called hash.lst

$6$jvhsGKzr$DJ.V8JMWBvZjyelp12htqtsgAIL.Al.feDI3nujmlWocBERWCEQlRjj39y2QyxKsbl85up0GZkl6H2eItH9BS1

I have also created a small wordlist called small.txt which contains the correct password 12345

Running hashcat with the following command does not find any results

sudo ./cudaHashcat64.bin  -m 1800 -a 0 "/home/tommy/hash.lst" "/home/tommy/wordlists/small.txt"

I am probably doing something really stupid, but would really appreciate if someone could point me in the right direction.

Thanks
